Ok so my father is a child molester and I know the type of guilt you're talking about. First off as everyone says its not your fault,. I know easy to say but not so easy to believe. Pretend you are someone else telling yourself your story.. What would you tell her?
There is another part of this that I came in touch with in therapy.. Another reason the guilt is heavy. You still love your dad, hard to explain. Why love a monster? It must be because I have fault in this.. No wrong. Ok imagine your Memories with your father are all in a box. There will be black sections for the bad and white for the good. Some of the white made who you are today so it okay to love those parts.
My suggestion to you, once you feel ready go to therapy (i wasn't big in therapy until I saw first hand how help ful it can be) you don't need to publicly anounce but seeing a therapist can go a long way.
Wishing you the best -xo
